7. CONNECTION TO FA NETWORKS
To attach a communication cable to the DeviceNet interface connector,
follow this procedure.
(1)Remove the sheath of the cable to a length of about 30 mm, and cut
off the excess shielding.
(2)Remove the aluminum tape from around the signal and power supply
wires. Also remove the insulator from each wire to a length of about
(3)Twine the stripped signal wire strands. Also twine the stripped power
supply wire strands. Attach a crimp terminal to each bundle of wire
To crimp the terminal, use a crimp tool complying with JIS C9711 by
setting its indication to 1.25.
Recommended crimp tool:
HR31–TC–01 manufactured by Hirose Electric Co., Ltd.
(4)Insert the shielding wire, signal wire, and power supply wire into the
plug by matching their insulator colors to the color codes indicated on
When attaching each crimp terminal to the plug, keep them in the
orientation shown below.

(5)Insert the plug into the DeviceNet board, and fasten it with its bolts
using a No. 0 cross–head bit.
These crimp terminals are of a multidrop type. Each terminal can be used
to crimp two thin cable wires together. They are not for thick cables.
If you made a misconnection, correct it by pulling out the crimp terminal
according to this procedure.
A rod 1 mm in diameter can be used to pull out a crimp terminals.
Recommended tool: HR31–SC–TP manufactured by Hirose Electric
(1)Push a pull–out tool against the molded lance. (See Fig. 1.)
(2)While pushing the molded lance, tilt the pull–out tool to release the
crimp terminal lock. (See Fig. 2.)
(3)Pull out the pull–out tool.
(4)Pull the wire to take out the crimp terminal.
